STRAW-CUTTER.

Specification of Letters Patent No. 26,554, dated Dec embe r 2'7;

To all whom it may concern:

Be' it known that we, W. H. BAKER,

DANIEL DEAN, and B. L. FETHEROLF, of Tamaqua, in the countyiof Schuylkill and State of Pennsylvania, have invented a new and Improved Straw and Stalk Cutter; and

,we do hereby declare that the following is. a full, clear, and exact description of the same, reference being had to theannexed drawings, making a part of thisspecification, in which- Figure l, is a front view of our invention. Fig. 2, a slde sectlonal view of dltto, taken.

in the line w, w, Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.

The object of this invention is to obtain a machine that will cut hay, straw and stalks for fodder with great rapidity, perform the work well, and be capable of having certain parts graduated so as to regulate as may be desired the length of the pieces into which the stuff is to be cut.

The invention consists in the employment or use of a double-edged reciprocating knife,

feed mechanism, and pressure bed, arranged.

substantially as hereinafter described.

' To enable those skilled in the art to fully understand and construct our invention we will proceed to describe it.

A, represents a rectangular feed box which n is supported at a suitable height by any proper framing the front uprights a a, of which extend above the feed box and form guides for a knife frame B, in which a double-edged knife C, is placed obliquely as shown clearly in Fig. 1. The upper end of the frame B, has a vertical bar 6, attached to it at thenupper and lower ends of which there are rollers 0, 0. Between the two rollers c, c, an annular rim d, works. This rim is attached eccentrically to a wheel D, the shaft 6, of which has its bearings on the upperends of the uprights a, a, the bar b, be-.

ing slotted vertically to allow the shaft 6, to pass through and at the same time permit the bar to work up and down. t

On one end of the shaft e, there is placed a bevel toothed wheel E, which gears into a pinion F, on the upper end of an oblique shaft G, the lower end of which has a bevel pinion f, on it, which pinion gears into a corresponding pinion g, placed on a horizontal shaft h, underneath the feed box. The shaft h, has an eccentric H, on it which works in a yoke I, said yoke being attached to a slide J the backpart of which works; on a rod or shaft i,,as sho lwn inl Fig. 2.

To the upper surface of the slide Jfan elastic plate K, is attached and tothe front 608; part of this platea bariL, is secured, said 1 bar having its upper surfaceuprlovidedwwith; H vertical spikes. The bar. L, is equal inlength to the width oftthe feed box A. 1

To the lowerparts offthe .uprightsgmk a lever frameM, lSIS BOIl I'G dLW Theinner en of this frame is providedwitlr across pin'j which is fitted between guidesglc, 7c, atth lower part of the yoke-I., 1Against thecfront the leverframe M, neil lf itsfouterendzt bars 0, 0, are attached thelupperendsfo which are connected to rods ll, Z, whichfpass through slots in the sides of the feed boxand are attached to a board or bed P,in the feedbox. jl Within the feedbox a roller1Q, is placed; said roller having its journalsfitted inyield 1 ing bearings m, a, each of which has al spring R,.bearing on its upper surface. 1

The bars 0, 0, are eachififormed of twow f1 g pieces connected by springs 71,, n, and on the) shaft 2', 011 which the backpart, of the slide 1 J, reststhere is placedfan, eccentric plate o.) 1; The operation of the machine is asfollows :-The operator places the straw, stalks I; f or other substance to be-cut,*shown in reds; f in the feed box A,.and. motionfisgiven: they f shaft 6, by any convenienty power. A ref ciprocating motion isgiven theknife frame .90 B, by the annular rim d, fittingbetween the. it rollers c, c, on the vertical bar 6, andflfrom l the shaft 6, motion is communicated to the shaft by the gearingwEQ FQ f, f g. j As the shaft h, rotates theeccentricj actuatesfthe, H yoke I, and gives a compound movement 1: the toothed barL,viz, andyup and dow; and lateral movements: This movement of, bar L, feeds the straw, stalks or other sub-, stanceto be cut underneath the bedylPytofl the knife 0, and the length ofathis move ment may be regulated turning shaft 2,. so that. the major diameter of theeccentric plate 0, may be adjusted: more or .lessiinl. line with the slide J and;thereby,determinev the length of its vibration; Askthe knife C, i J vibrates, the bed P,]-isalsogjmovedlupfand down by the lever aframefM, and bars 0, o.1 The bed P, serves pressgon the uppersur face of the straw or! stalksiwhen thelzknife 11C is effecting its out and"consequentlyiwhenl I; the knife is descending, the bed P,descends,

the bed also descending as the knife rises. This movement of course is effected by having the lever frame M, and mechanism which operates it properly arranged. The straw or stalks are cut between the bed P, and the front end a", of the bottom ofthe feed box. By having the bars 0, 0, formed of two parts connected by springs n, due provision is made for irregularity in the thickness of the straw or stalks being cut, and the bed and its operating mechanism will consequently not be subjected to any undue strain thereby. The straw or stalks may be cut into pieces of greater or less length bycontrolling the lateral movement of the slide J, which is effected by turning the shaft 2', and properly adjusting the eccentric'plate 0, relatively with the slide J The spring N, keeps the front part of the yoke in contact with the eccentric, the former being somewhat larger than the diameter of the eccentric in order to admit of the variation in the length of the longitudinal movement of the slide J, for varying the length of the feed. The roller Q,

slightly presses on the straw or stalks and causes the same to be fed properly underneath the bed P.

Having thus described our invention what we claim as new and desire to secure by Letters Patent, is,

1. The double-edged reciprocating knife C, in connection with the bed P, arranged to operate substantially as and for the purpose set forth.

2. The arrangement of the eccentric H, yoke I, slide J, lever frame M, and bars 0, substantially as shown and described for operating conjointly the feed bar L,.and pressure bed P.

3. The eccentric plate 0, placed on the shaft 71, when used in connection with the slide J, to control its longitudinal move ment for the purpose herein set forth.
